Symbols Used
CAUTION! Risk of electric shock. The voltage at the
parts marked with this symbol may be dangerous.
Warning: Risk of danger. Refer to the operating manual to find out the nature of
the potential hazards and the action necessary to avoid such hazards.
Earth/Ground
Dual insulation
The trash can with a line through it means that in the European Union, the prod-
uct must undergo selective disposal for the recycling of electric and electronic
material, in compliance with Directive WEEE 2002/96/EC.
The CE marking guarantees conformity with European directives and with regu-
lations covering EMC.
Application or withdrawal not authorized for non-insulated conductors carrying
dangerous voltage levels
Power Supply
The oscilloscope is supplied with one external power supply and set of 6 x 1.2V NiMH
rechargeable batteries 2700mA/h.
When the supplied wall plug is connected from the instrument to an external power
source, battery power is not needed. The batteries are only used when there is no
external power supply available.
Before the first use, start by fully charging the battery.
NOTE:
The batteries automatically begin recharging when the Oscilloscope is powered off, but
connected to an external power supply.
When the batteries are recharging, the Battery Charge LED on the front panel will turn
on steady.
The LED will blink in the following situations:
• pre-charge of very low batteries
• temperature is too low or too high
• batteries are damaged
When the charge is complete, the LED will turn off.
If the batteries need to be replaced, they must be replaced with NiMH rechargeable
batteries. Battery charge life is guaranteed for same-capacity batteries (in mAh) as
those shipped with the oscilloscope.
To remove the battery cover, use a coin to turn the slot on the back of the unit counter-
clockwise.
